SPS 5 Phase Change and KMT Flashcard

Front

What is the arrangement of particles in a solid?

Back

In a solid, the particles are closely packed together and vibrate in place.

Front

What is condensation in terms of phase change?

Back

Condensation is the phase change from gas to liquid.

Front

How do particle movements change with temperature?

Back

At higher temperatures, particles in an object move faster.

Front

What is the phase change from water vapor to liquid water called?

Back

The phase change from water vapor to liquid water is known as condensation.

Front

How do solids differ from liquids in terms of particle movement?

Back

Particles in solids vibrate in place, while particles in liquids can move past one another.

Front

What happens to the energy of particles during melting?

Back

During melting, the energy of the particles increases, allowing them to overcome their fixed positions.

Front

What is the process of a liquid turning into a gas called?

Back

The process of a liquid turning into a gas is called evaporation.

Front

What is the term for the phase change from solid to liquid?

Back

The phase change from solid to liquid is called melting.

Front

What occurs during freezing?

Back

During freezing, a liquid loses energy and its particles move closer together to form a solid.

Front

What is the kinetic molecular theory (KMT)?

Back

The kinetic molecular theory (KMT) explains the behavior of particles in different states of matter, stating that particles are in constant motion and that this motion is related to temperature.
